■
Overview
● The logging function is used to record arbitrary contacts and data information together with
time stamp information at any time, and save them in an SD memory card inserted in the
CPU unit.
● Log data is saved as csv format files.
● Use the Logging/Trace Settings menu of the tool software FPWIN GR7 to set the
conditions.
● The settings are downloaded to the PLC as a part of project data, and stored in the ROM1.
The setting data can be saved in SD memory cards and used.
● The logging operation is executed by any of these operations: (1) tool software FPWINGR7,
(2) dedicated instructions or (3) Autostart via setting.
● To perform data logging at high speed, the buffer memory in the CPU unit is used.
